Port 8
The Ethernet switch carries traffic already marked with VLAN tags with
priorities. The threshold set on the HUB(8) ETU in MB 1-16-07 is priority 4.
Priority 0~3 traffic from the Ethernet Switch goes to the Low Priority queue
of the HUB(8), and priority 4~7 goes to the High Priority queue. For traffic
from ports configured for port-based priority that exit port 1, the Low Priority
queue traffic is marked priority 0, and the High Priority queue traffic (from
the MG(8) on port 4 and the IPC on port 6) is marked priority 4. The
Ethernet switch is configured for special handling of priority 4 traffic and
priority 5 traffic for the IP telephones off the HUB(8) on its adjoining port.
